The writing magic actually happens in my imagination, but we can pretend it's here. After all, this site is all about the wonderful world of fictional dreams and exciting adventures, so really, the magic can happen anywhere.
I am currently working on new books in the Montana Gallagher series, British Agent series, Crooked Creek series, and a new series set in 1890s Colorado, which will be written with another author. I am also in the planning stages of a dual-timeline novel and historical Highland series. I have enough projects on the planning board to keep me busy for many years.
The process of writing a story is fun and messy and riddled with mistakes and changes. I may get halfway through a book before I feel the story needs to go in another direction in order to remain true to the characters. I've tossed out half a book (2 books, actually) before when it didn't feel right. These are among the many reasons why I don't share details about my various works-in-progress until I get closer to a completion date.
I write in a combination of longhand and typing, which means sometimes the writing is really fast and other times snail-paced slow. Some years I may write one book, other years it may be two or three, and if life requires it, a year may be skipped. Each book takes as long as it takes.
